Beautiful.ai

An AI presentation tool from the US-based Beautiful Slides where putting content on a slide automatically arranges the layout and design.

ガンマ

GAMMA

GAMMA is an AI design partner that generates everything from presentation decks, documents, and websites to social posts and graphics, all from a prompt (provided by Gamma Tech, Inc.). Drawing on your ideas, outlines, or existing materials, it automatically generates the design too using 20+ AI models and 100+ themes, with export to PPT/PDF/Google Slides and web publishing. Pricing includes a free plan plus Plus at ¥1,440/mo, Pro at ¥2,500/mo, and Ultra at ¥13,274/mo (billed annually, per user, excluding tax). Used by more than 100 million people worldwide.

コピースライド

CopySlides

CopySlides is a web service from AxisLab, a company established in Hong Kong SAR, that converts slides trapped in images, PDFs, and videos into editable PowerPoint (PPTX) files. There are three routes in: a Chrome extension that runs inside NotebookLM, an upload route for exported PDFs, and a route that extracts slides from a recorded video. Microsoft Azure AI Vision handles the text recognition, and an AI model rebuilds the layout as text boxes, tables, and shapes. It can also turn an image into a layered PSD. Pricing is Starter at $9/month (200 slides), Plus at $19/month (600 slides), and a one-time Lifetime plan at $149, with 3 free credits on registration. The interface is English only.

デックエディット

DeckEdit

DeckEdit is a free web tool that converts image-only slides — the decks NotebookLM (now Gemini Notebook) generates, plus PDFs and screenshots — into editable PowerPoint (PPTX) files. Text detection, recognition, background cleaning and PPTX assembly all run inside your browser, so files are never uploaded to a server. No account, no login and no payment are required, there is no watermark and no cap on conversions, and it keeps working offline once the AI models have been cached on first use. It accepts PDF, PNG, JPEG, GIF and WebP up to 30 MB and 50 pages per file, offers a Japanese interface and Japanese OCR, and includes a browser-based editor for text, shapes and speaker notes.

キリガミ

Kirigami

Kirigami is a web service and API, run by an individual in Japan, that converts images and PDFs into editable PowerPoint (PPTX) files. OCR restores the characters inside an image as text boxes you can rewrite, shapes are vectorised, and related elements are grouped through what the service calls Stack Mode. Multi-page PDFs can be submitted in one go and reconstructed slide by slide, and the same conversion can be called from a REST API, a CLI, MCP or Claude Skills. The interface and output are available in 17 languages. Pricing runs on credits: one image costs 10 credits, and monthly plans start at $12.00 with STARTER (as of September 2026).

ノートスライド

NoteSlide

NoteSlide is a slide conversion service from Codia Tech, LLC in the United States. It analyzes PDFs and image slides exported from NotebookLM (now Gemini Notebook) with "Codia AI Vision" and outputs a .pptx in which headings, body text and shapes have been rebuilt as editable PowerPoint elements. The exported file opens directly in PowerPoint, Keynote and Google Slides. It recognizes 109 languages including Japanese, and the site can be switched to Japanese. Beyond conversion, the same screen offers Generate Slides, which builds a deck from a brief or your own files, and Redesign Slides, which rebuilds an existing deck under one template. The Free plan includes 5 credits per month (1 credit = 1 output slide); paid plans start at $20/month for Starter, or $12/month billed yearly, both before tax (as of September 2026).

スウィフトスライド

Swift-Slide

Swift-Slide turns NotebookLM slides and image or PDF documents into editable PowerPoint (PPTX) files. It works for slides generated by NotebookLM (now Gemini Notebook) as well as documents whose original files no longer exist, keeping the design intact. It removes the text read by OCR, restores the background with AI, and places the text back in its original position as editable text, so you can fix the wording, position, and fonts in the browser and export to PPTX, PDF, PNG, or JPEG. It is provided by Swift-Triad LLC. You can try one page without signing up, and pricing is Free (5 pages/month), Light ¥980/month, Standard ¥2,980/month, and Team ¥9,800/month (tax included). Available in Japanese and English.

How to Edit NotebookLM Slides [September 2026]: Why You Can't Fix the Text Even in PPTX, and Five Methods by What You Need to Change

NotebookLM (renamed Gemini Notebook in July 2026) produces slide decks that are "a single picture with text in it", drawn by the image generation model Nano Banana Pro. Whether you export to PDF or PowerPoint (PPTX), each slide goes in as an image, and export to Google Slides is still not available as of September. This article confirms from Google's official help that the official Revise feature rebuilds the entire slide deck every time and does not consult your sources during revisions, then sets out five methods you can choose by what you want to fix: giving instructions with Revise; laying corrections over the top in PowerPoint; conversion tools that use OCR to turn slides back into a PPTX with editable text (comparing pricing and data handling for NoteSlide, Kirigami, DeckEdit, CopySlides and Swift-Slide); redrawing the slide as an image with Nano Banana; and rebuilding it as an editable deck with tools such as GAMMA or Irusiru. It also covers caveats such as Canva's Grab Text not working on Japanese slides, the compute-based limits in place since 2 September, and how watermarks are handled.
